After the potatoes get cut off from the roots upon harvest, we assume that they stop breathing. The fact is, they never cease to do so.

The oxygen combines with their sugar content, releasing carbon dioxide. This accelerates their decay. Storing potatoes properly prevents the production of CO2 and also retains their vitamin C content.

Other Causes Of Potatoes Spoilage

  • Microorganisms: Injured potatoes become prone to yeast and mold. These contaminate other potatoes as they are stored together.
  • Moisture: Potatoes are 80% water, so they need humidity to stay hydrated, but excess moisture fosters the growth of bacteria, causing potatoes to rot.
  • Light: This turns potatoes green due to chlorophyll and also increases the production of solanine, a chemical toxic to humans.

Grating & Freezing

This is ideal for making hash browns. Wash, peel, grate, then cool potatoes in ice-cold water. While they cool, bring water in a pot to a boil. Transfer the grated potatoes into the hot water then blanch them for 2 to 3 minutes. Drain and shape into patties. Freeze. Put in a sealable bag, then refreeze.  

Cutting Potatoes Into Fries Then Freezing

This will add extra crunch to fries. Peel, slice the potatoes into your preferred thickness, then blanch them for 2 minutes. Plunge transfer into a bowl of ice-cold water then drain. Coat with vegetable oil, place in a baking tray, then freeze for 6 hours. Put into an airtight bag and refreeze.
